NOTE
•
When powering on after leaving the detector for more than five minutes with the batteries removed,
such as when powering on for the first time or replacing the batteries, or powering on with the
batteries inserted with incorrect polarities, the monitor enters the clock adjustment mode. In such a
case, see "Date/time setting" on page 35 and set the date/time.
•
Warm-up time (WARM UP) is different depending on the stability status of the sensor.
•
If the detector is not used for a long period, warm-up time may be longer or a sensor abnormality
(FAIL SENSOR) may be displayed. In such a case, restart the detector.
•
The detector performs an air calibration automatically on start-up. If an environment where the
detector is turned on is different from the measured atmosphere, perform air calibration again in the
measured atmosphere.
